Well, given that a quarter equals 5 nickels, we can reason that, in order to get 12 coins, we would have to get 10 nickels (equals 50 cents) and 2 quarters (the other 50 cents, to make a dollar).
You didn't say whether you needed this expressed in a mathematical formula, but knowing the answer already, it shouldn't be hard to come up with one if necessary.
Hope this helps.

Answer:
1,000,000,000 leaves or 1 x 10^9 leaves
Step-by-step explanation:
One large oak tree has 2 x 10^5 leaves, so we can make that number to 200000
There are 5 x 10^3 oak trees in a forest, we can make that number to 5000
Since we want to find out how many leaves are in the whole forest we multiply: 200000 x 5000 = 1,000,000,000
So approximately there are 1 billion leaves or 1 x 10^9 leaves
Initial dep for A = $200
for A, B, C :
initial dep + 6 (monthly rent) = $5150
For A:
$200 + 6(monthly rent A) = $5150
monthly rent A = (5150 - 200) / 6 = $825
For B:
monthly rent B = monthly rent A - $25 = $800
initial dep B + 6(800) = 5150
initial dep B = 5150 - 4800 = $350
For C:
initial dep C = initial dep B + $150 = $500
$500 + 6(monthly rent C) = 5150
monthly rent C = (5150 - 500) / 6 = $775
